Walmart only had 5W-20 and 10W-30!

No 5w30 to be seen. So, dealing with my small-block Chevy, I stood there for a good 5 minutes, thinking it through.. and got 10w30.

The cheapest stuff on the shelf. I did not look to high mileage or synthetic oils.

Would you have dine the same, if the only choices were 5W-20, 10w30, 15w40, and 20W-50 Supertech? Why would 5W-20 be bad in a 350SBC? (5.7L)

It'll be fine. I use Valvoline 10w30 conventional in my gf's Mustang that calls for 5W30.

Check around...there should be another store in your town that has 5w30.

In the summer it's less of a big deal. Going into the warmer months I probably would have gone with the 10w as well. Actually, I prolly would have found a high mileage that was 5w. But if that could not be found, 10w is fine.

Summer is coming, you made the correct choice. Not worth driving all around to find 5w30.

How big is the oil section at your walmart? There's a million different 5w30s at the walmarts around here!

Go online to Walmart......select the Ultra product you want ....... and then keep changing Walmart store locations until you find one that has the correct oil in stock.

P.S. As an option, some Forum members are mixing Pennzoil Ultra 10w30 with a little 5W-20 to create a 5w30 blend.

Last resort is to use PP for slightly shorter OCI's as its additive package is 8 to 10% lower than Pennzoil Ultra. (Basestock isn't as good as Pennzoil Ultra's either.)

Walmarts are not always good with keeping the shelves stocked.
The 10w30 is fine for your engine in warm weather.
Heck, it was the default grade for the SBC for many years.
I use clearance or FAR 10w30 myself in applications where 5w30 is the prefered OM recommendation.
No harm in using it in warmer conditions.

 

[Lyman]

I use the 10w30 all the time. I don't know why it bothers you at all.

 

[EA82]

Yeah walmarts employes don't do a very good job at stocking the oil shelves.

 

[davebarnum]

Get both and mix em?

But if they had 5w30, I wouldn't see the point in going against the recommendation.

Since the winter in NJ is over, 10w30 will be okay.

I hope it was a good brand of oil an not ACCELL SE rated oil.
You mentioned cheap .
